Category:

Description

FEATURES

  • Measures ground resistance (2- and 3-Point) Fall-of-Potential method and soil resistivity (4-Point)
  • Fuse protection of 0.1A, >250V, 0.25 x 1.25″ with 30kA Interrupt Capacity
  • Both models will perform over 2,000 measurements of the 15-second tests between recharging or battery replacement
  • Provides a response time of approximately four to eight seconds for a stabilized measurement
  • Step voltage tests and touch potential measurements
  • Auto-ranging: automatically selects the optimum resistance range and test current
  • Designed to reject high levels of noise and interference
  • Extremely simple to operate: connect – press – hold – read
  • May also be used for continuity tests on bonding
  • Large easy-to-read backlit display
  • LED on faceplate informs operator of high input noise, high auxiliary rod resistance and fault connections
